Type: User manual

SKC 225-9007 preloaded coated filters simplify air sampling for mercaptans and phenyl-mercaptans. These filters come ready to use, eliminating the need for assembly. They feature a glass fiber filter coated with mercuric acetate and are designed for use with a two-piece 37-mm cassette in a closed-face sampling configuration. With a storage temperature of ≤ 39.2°F (4°C) for up to 8 months and sample stability of up to 15 days when stored at the same temperature, these filters offer reliable and convenient air sampling solutions.

How to Use SKC Preloaded Coated Filters

Ensure that filter cassettes are at room temperature

before sampling.

1. Select one coated filter cassette for calibrating the flow rate. A red plug

secures the inlet, which is clearly marked “inlet,” and a blue plug

secures the outlet. Set up the sampling train for calibration with the

representative filter cassette in line. For “closed-face” sampling, remove

the plugs and connect the cassette to the sampling train. For “open-

face” sampling, remove the outlet plug and the cassette inlet section and

then connect the cassette to the sampling train. For details on setting up

a sampling train, refer to the SKC Sample Setup Guide “Sampling Train

– Filters” at www.skcinc.com/knowledgecenter.

2. Calibrate the pump to the desired flow rate using a calibrator.

3. Replace the cassette used for calibration with a fresh coated filter

cassette for sample collection. Attach the cassette to a worker’s collar,

as close to the breathing zone as possible, by using a filter cassette

holder SKC Cat. No. 225-1. Sample for the specified time interval and

record the time.

4. Remove the filter cassette at the end of the specified sampling period

and replace both end plugs (and the inlet if necessary). Recheck the

flow rate using the same cassette and calibrator used for calibration in

Step 2 to ensure that the flow rate has not changed by more than 5%.

5. Store samples at ≤ 39.2 F (4 C) for up to 15 days. Appropriately

package samples, blanks, and all pertinent data to send to a laboratory

for analysis. Expedite shipping of samples to laboratory. Friday

shipments are not recommended.
